using quickref.me for quick syntax checks
quickref.me for quick syntax checks
I use cheatsheets when I already know what I am trying to do, but I do not remember the exact syntax.
That happens a lot with small things:
- Python slicing or f-strings
- Git commands I do not use every day
- Docker flags
- regex anchors and character classes
quickref.me is useful for that kind of lookup. It has short reference pages for programming languages, command-line tools, databases, Linux commands, keyboard shortcuts, and web basics like HTTP status codes.
I do not treat it as official documentation. I treat it as a fast reminder.
quickref.me and cheatsheets.zip
The quickref.me page links to the open source Fechin/reference repository. The repo notes that cheatsheets.zip is now the maintained domain.
So the simple version is:
- quickref.me is the familiar URL.
- cheatsheets.zip is the maintained version.
- official docs are still better for production details.
That is enough context for how I use it.
Python
The Python cheatsheet is useful for quick reminders around strings, lists, dictionaries, loops, functions, files, f-strings, and slicing.
Example:
name = "quickref.me"
items = ["python", "git", "docker"]
print(f"{name} has {len(items)} references")
print(items[:2])
This is basic Python, but that is usually what I want from a cheatsheet. I am not looking for a full tutorial. I just want the syntax back in my head.
Regex
The regex cheatsheet is useful because regex is easy to half-remember.
Example:
^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,}$
That pattern is not perfect email validation. It is only an example of the pieces:
^starts the match.[a-z0-9._%+-]+matches one or more local-part characters.@matches the separator.[a-z0-9.-]+matches a simple domain shape.\.matches a literal dot.[a-z]{2,}matches a simple top-level domain shape.$ends the match.
For regex, I always test with real input before using it.
Git
The Git cheatsheet is good for checking command shape quickly.
Example:
git status
git diff -- README.md
git add README.md
git commit -m "Document quickref.me workflow"
For normal status, diff, add, commit, branch, stash, and log commands, a cheatsheet is fine. For history rewrites or remote changes, I slow down and check the real docs or the project workflow.
Docker
The Docker cheatsheet helps when I am debugging local containers.
Example:
docker ps
docker logs --tail 50 web
docker exec -it web sh
That gives me a quick path:
Check the container.
Read recent logs.
Open a shell inside it.
For Dockerfiles, networking, volumes, Compose behavior, or deployment work, I still use Docker’s documentation.
My rule
I do not copy cheatsheet examples blindly.
I use this flow:
- Find the command or syntax.
- Adjust it to the current task.
- Run a small safe check.
- Use official docs if the detail matters.
That is where quickref.me works well for me. It removes small lookup friction without pretending to replace the docs.
